2-氨基-4-硝基苯甲酸主要用作有机合成和医药化学中间体,可用于生物活性分子和药物分子的合成。
制备方法向装有磁性搅拌棒的Schlenk管中加入CuI(0.1 mmol,19 mg)、NaN3(4 mmol,260 mg)、Cs2CO3(2 mmol,652 mg)和N-(2-溴苯基)乙酰胺衍生物(1 mmol)。将试管抽真空并用氮气回填两次。然后在氮气流下,在室温下依次加入乙醇(5 mL)和N,N-二甲基乙二胺(DMEDA)(0.2 mmol,18 mg),密封试管。将反应体系放入95℃的热油浴中,搅拌反应12至56小时。
反应结束后,将所得溶液冷却至室温,在真空下蒸发除去溶剂。然后加入5 mL盐酸(1 N)以酸化溶液(pH 2-3),用乙酸乙酯(3×5 mL)萃取反应混合物,浓缩合并后的有机相。使用石油醚/乙酸乙酯(2:1)在硅胶上进行柱色谱法纯化残余物即可得到目标产物2-氨基-4-硝基苯甲酸。

The efficacy and side-effects of drugs do not just reflect the biochemical and pharmacodynamic properties of the parent compound, but often comprise of cooperative effects between the properties of the parent and active metabolites. Metabolites of imatinib, nilotinib and midostaurin have been synthesised and evaluated in assays to compare their properties as protein kinase inhibitors with the parent drugs. The N-desmethyl-metabolite of imatinib is substantially less active than imatinib as a BCR-ABL1 kinase inhibitor, thus providing an explanation as to why patients producing high levels of this metabolite show a relatively low response rate in chronic myeloid leukaemia (CML) treatment. The hydroxymethylphenyl and N-oxide metabolites of imatinib and nilotinib are only weakly active as BCR-ABL1 inhibitors and are unlikely to play a role in the efficacy of either drug in CML. The 3-(R)-HO-metabolite of midostaurin shows appreciable accumulation following chronic drug administration and, in addition to mutant forms of FLT3, potently inhibits the PDPK1 and VEGFR2 kinases (IC50 values
